What are the key technical points for fattening Hu sheep? A detailed explanation in one article

The Hu sheep is one of the important livestock in the Taihu Plain and is a first-class protected local livestock and poultry breed in China. It is a rare white lambskin sheep breed, with excellent traits such as early maturity, estrus in all four seasons, two litters per year, multiple lambs per litter, good lactation performance, fast growth and development, ideal meat production performance after improvement, and tolerance to high temperature and high humidity. It is distributed in the Taihu region of China and is a sheep breed raised in sheds year-round for lambskin in China. The small Hu sheep skins from lambs slaughtered and stripped 1 to 2 days after birth have beautiful patterns and are renowned worldwide. The economic benefits of Hu sheep are very high, so how are Hu sheep fattened?

First, select, exchange and promote improved breeds. Rams and ewes with large body size and excellent meat production performance should be selected for breeding. While introducing and exchanging breeds, actively promote artificial insemination to increase the proportion of improved breeding sheep and increase the birth weight of lambs.

Second, adjust the lambing season. On the one hand, breed spring-mated ewes appropriately earlier, advancing from the original May to June to April, so that the lambing season is moved up to early October; on the other hand, change the breeding period of some ewes to autumn, realizing a pattern of autumn mating, spring lambing and winter marketing. Lambs born in spring are marketed after autumn, which not only increases meat production but also improves the flavor of the mutton.

Third, implement one ewe with two lambs to increase the number of retained lambs and fat lambs. Hu sheep are capable of nursing twin lambs, and leaving twin lambs for ewes in healthy body condition can greatly increase the proportion of lambs. At the same time, do a good job of supplementary feeding. For each fat lamb, in the 2 months before sale, feed 100-125 grams of concentrate and roughage per day. The diet is composed of a mixture of green grass, dried grass and rice bran, and can also be supplemented with 3% rapeseed meal and 0.3% table salt. The fattening period for fat lambs should be kept at about 220 days, and the marketing body weight can reach 35-37 kg.

Fourth, conscientiously carry out epidemic prevention and deworming. Keep the sheep shed dry, clean, with clean drinking water, and prevent pollution. Persist in deworming in both spring and autumn. Deworming methods: 1. Subcutaneous injection of Miechongding injection, inject 1 milliliter for a body weight of 40 kg. 2. Mix Miechongling into feed for feeding, use 1 gram for a body weight of 3 kg.
